Amy Poehler showed up to help Seth Meyers say goodbye to "Saturday Night Live" earlier this month so it was only fitting for the comedian to serve as her friend's first guest as he kicked off his new "Late Night" hosting gig this week.

Meyers started the show with a cold opening that paid homage to a regular Fallon bit, "Thank You Notes."

"Thank you Jimmy Fallon for taking over 'The Tonight Show' at 11:30 so I could take over 'Late Night' at 12:30," Meyers said. "I promise to treat it with respect and dignity and to only use it to do completely original comedy pieces. Starting now."

From there, he welcomed "Parks and Recreation" star Poehler. The two started on "SNL" together in 2001 and helmed the coveted "Weekend Update" desk from 2007 until the actress left the show in 2008.

On Monday's "Late Night," Meyers also interviewed Vice President Joe Biden, who took the opportunity to promote train transportation in the U.S.

"The monologue was basically a standing up version of 'Weekend Update' — eschewing many major topics for weird news — and I like Seth's 'Weekend Update' so I was okay with that," The Atlantic's Esther Zuckerman wrote. "He, naturally, looked a little uncomfortable, but was still miles more at ease than Jimmy was when he started out doing 'Late Night.'"

"The first night was all about softballs, but kudos to Seth for booking someone as notoriously difficult as Kanye for night two," The Atlantic's Connor Simpson wrote. "It’s a ratings gambit, but it could certainly backfire on the producers. Seth could be the best interviewer in late night. The potential is there, and tonight will be his first big test."
